In order to facilitate the interactive communication between the user and the PLC controller, it is necessary to achieve this goal through the Human Machine Interface (HMI), equipped with a color touch screen or a desktop industrial PC.
Control systems used in the pharmaceutical industry shall be designed, constructed and tested in accordance with the applicable GAMP guidelines, GMP Appendix 11, and Part 11 of CFR21. The main topics required by CFR21PART11 are to ensure the security, integrity and non editability of data, including ensuring appropriate access levels for various user groups, and recording events in the form of "audit trails".
◆ Ensure data integrity and security.
◆ User interface is easy to operate.
◆ Function automation to minimize human-computer interaction.
◆ Save time and cost.
◆ The PLC controller can be connected with the factory monitoring system through the common communication system.
◆ Use the latest GAMP to develop software.
◆ SCADA system in pharmaceutical industry complies with relevant requirements of CFR 21Part 11.
